Oxidative phosphorylation yog cov txheej txheem uas ATP yog tsim raws li electrons raug pauv los ntawm cov ntaub ntawv txo ntawm nicotinamide adenine dinucleotide ( NADH thiab flavin adenine dinucleotide ( FADH 2 ) mus rau molecular oxygen (O2) los ntawm ib tug series ntawm electron transporters (piv txwv li lub electron thauj saw).
Tsis tas li ntawd, dab tsi tswj oxidative phosphorylation?
Cov kev cai ntawm tus nqi ntawm oxidative phosphorylation los ntawm qib ADP yog hu ua kev tswj kev ua pa lossis kev lees txais. Qib ntawm ADP zoo li cuam tshuam rau tus nqi ntawm lub voj voog citric acid vim nws xav tau NAD+ thiab FAD.
Qhov thib ob, yog vim li cas oxidative phosphorylation tshwm sim? Oxidative phosphorylation yog cov txheej txheem uas ATP yog tsim los ntawm kev hloov ntawm electrons los ntawm NADH lossis FADH 2 rau O 2 los ntawm ib tug series ntawm electron cab kuj. Cov txheej txheem no, uas tshwm sim hauv mitochondria, yog qhov loj ntawm ATP hauv cov kab mob aerobic (Daim duab 18.1).
Ib yam li ntawd, lub ntsiab lus twg yog qhov tseem ceeb rau oxidative phosphorylation?
oxygen
Dab tsi yog oxidative phosphorylation tseem hu ua?
kws d. ?. t?v/, US /ˈ?ːk. s?ˌde?. t?v/ lossis electron transport-linked phosphorylation ) yog txoj hauv kev metabolic uas cov hlwb siv cov enzymes los oxidize cov as-ham, yog li tso lub zog uas siv los tsim adenosine triphosphate (ATP).

Puas yog oxidative phosphorylation zoo ib yam li electron thauj saw?
Oxidative phosphorylation yog tsim los ntawm ob qho kev sib txuas zoo sib xws: cov saw hlau thauj hluav taws xob thiab chemiosmosis. Hauv cov khoom siv hluav taws xob thauj khoom, cov khoom siv hluav taws xob tau dhau los ntawm ib lub molecule mus rau lwm qhov, thiab lub zog tso tawm hauv cov hluav taws xob hloov hluav taws xob no yog siv los tsim cov tshuaj electrochemical gradient
Oxidative phosphorylation yog dab tsi thiab nws tshwm sim qhov twg?
Oxidative phosphorylation yog ib txoj hauv kev rau ATP synthesis hauv cov nroj tsuag thiab tsiaj txhu. Nws suav nrog chemiosmotic coupling ntawm electron thauj thiab ATP synthesis. Oxidative phosphorylation tshwm sim hauv mitochondria. Lub mitochondrion muaj ob daim nyias nyias: ib daim nyias nyias thiab ib daim nyias nyias
Dab tsi yog txhais los ntawm oxidative phosphorylation?
Lub ntsiab lus ntawm oxidative phosphorylation: lub synthesis ntawm ATP los ntawm phosphorylation ntawm ADP rau lub zog yog tau los ntawm electron thauj thiab uas tshwm sim nyob rau hauv lub mitochondria thaum lub sij hawm aerobic ua pa
Ob theem ntawm oxidative phosphorylation yog dab tsi?
Oxidative phosphorylation tshwm sim nyob rau hauv ob kauj ruam: electron thauj saw thiab chemiosmosis
Mitochondrial oxidative phosphorylation yog dab tsi?
Oxidative phosphorylation (UK /?kˈs?d. ?. s?ˌde?. t?v/ lossis electron transport-linked phosphorylation) yog txoj hauv kev uas cov hlwb siv cov enzymes los oxidize cov as-ham, yog li tso tawm lub zog uas siv los tsim adenosine. triphosphate (ATP). Hauv feem ntau eukaryotes, qhov no tshwm sim hauv mitochondria
